Chemical equation of magnesium belt burning in air

The chemical equation of magnesium belt burning in air is: 2Mg+O2 ignition? →2MgO .

Magnesium is an active metal element, which can react with oxygen in the air at room temperature to form a dense oxide film-magnesium oxide. When the magnesium belt burns, the situation becomes more intense. Magnesium reacts exothermically with oxygen to produce magnesium oxide. This reaction will release a lot of heat energy, accompanied by the production of light and smoke.

Magnesium can also react with carbon dioxide and nitrogen in the air to produce corresponding compounds. Magnesium reacts with carbon dioxide to produce magnesium oxide and carbon, and magnesium reacts with nitrogen to produce magnesium nitride. Although these reactions are not as violent as those with oxygen, some phenomena can be observed, such as some smoke or flames produced during combustion.

The burning phenomenon of magnesium belt in air is slightly different from that of pure oxygen. When burning in pure oxygen, the combustion is more intense, the flame is brighter and more smoke is produced. At the same time, because magnesium belt burns faster in pure oxygen environment, more attention should be paid to safety.

Application of magnesium belt in daily life;

1, fireworks and flares: magnesium tape emits strong white light when burning, so it is widely used in fireworks and flares. In fireworks display or celebration, people often use fireworks containing magnesium powder. Magnesium powder will burn violently after being ignited, giving off dazzling white light and creating amazing visual effects.

2. Fireworks show: In fireworks show, magnesium tape is often used to produce bright white light effect. In addition, because the magnesium belt will generate a lot of heat energy when burning, it can also display patterns such as steps, shapes or letters at night, providing an unforgettable visual experience.

3. Photography: Magnesium tape can also be used for photography. Because of its high reflectivity, magnesium tape can be used as the internal reflective material of reflective umbrella to improve the efficiency of flash lamp. In addition, magnesium tape can also be used as a filter, which can filter out a part of light and make photos produce a special effect.
